BarCodeReadPreprocessOptions Enumeration

Summary

Indicates the binarization method used for converting the image to black and white.

Syntax

Objective-C

C++/CLI

Java

[FlagsAttribute()] 
public enum BarCodeReadPreprocessOptions

typedef NS_OPTIONS(NSUInteger, LTBarCodeReadPreprocessOptions)

public final class BarCodeReadPreprocessOptions 
    extends java.lang.Enum<BarCodeReadPreprocessOptions>

[FlagsAttribute()] 
public enum class BarCodeReadPreprocessOptions

Members

Value	Member	Description
0x00000000	UseDefault	Use the best method for the detected barcode.
0x00000002	UseAutoDocumentBinarization	Use document image binarization.
0x00000004	UseDeblurBinarization	Deblure image before binarization.
0x00000008	UseFastModeBinarization	Use fast deblurring method.

Remarks

Using the default flag detects the best binarization methods for the detected barcode.
